High resolution powder diffraction on Sm based pyrochlores

Magnetic frustration is a hot topic in solid state physics, mainly due to the topological new phases of matter that frustration mechanisms can drive (vide Physics Nobel Prize...磁阻挫（magnetic frustration）是固态物理学领域的热门研究方向，其备受关注的核心原因在于阻挫机制可诱导生成拓扑物质新相——相关研究可参见诺贝尔物理学奖相关成果（原文表述未完整）。
